A theoretical relation is formulated by which the impulsive force generated at a contact part can be calculated, when an aluminium bar whose end is a circular truncated cone collides axially, perpendicularly against a plane wall at a comparatively low speed. In the formulation, the effect of the local behavior in the aluminium bar caused by stress wave propagation is neglected. By carrying out an experiment in which aluminium bars whose ends were of a variety of shapes of truncated cones, collided against a devised sensing plate, the effectiveness of the theoretical relation for calculating the impulsive force which varies complexly with the shape of the contact end and with the impact velocity is confirmed.
